Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Optical Tweezers or Dielectrophoresis methods are used to capture micro-particles, then capture and manipulation capability is achieved, but hardware cost and system complexity increase significantly
Solution Approach 1:
The patent replaces complex optical systems (laser, high numerical aperture lens) or electrical systems (RF pressure, plasma) with a simple hydraulic system consisting of a water jet nozzle and pressure control device. The water jet generates capture force through fluid dynamic effects, eliminating the need for expensive optical or electrical equipment while achieving the same micro-particle manipulation capability
Solution Approach 2:
The patent employs hydraulic principles by using a pressurized water jet to generate the capture force. The hydraulic device controls the pressure of the water jet, and the jet hole geometry is optimized to produce the desired fluid dynamic effects for micro-particle capture and manipulation, providing a simple and cost-effective alternative to optical or electrical methods
2Reliability
If Optical Tweezers or Dielectrophoresis equipment is deployed, then micro-particle manipulation is achieved, but implementation cost increases
Solution Approach 1:
The patent uses inexpensive components such as a simple water jet nozzle, pressure regulator, and hydraulic pump instead of expensive optical or electrical equipment. The water jet system can be easily manufactured and replaced, providing a cost-effective solution for micro-particle manipulation that is suitable for industrial applications
Solution Approach 2:
The patent substitutes expensive optical or electrical systems with a simple hydraulic system using water jet. This replacement dramatically reduces the manufacturing cost and complexity of the equipment while maintaining the capability to capture and manipulate micro-particles, making the technology accessible for industrial use
3Measurement precision
If specialized equipment like Optical Tweezers is used, then capture precision is achieved, but adaptability to different environments is reduced
Solution Approach 1:
The patent uses a hydraulic water jet system that can operate in various environmental conditions without requiring specialized environments. The water jet can be easily adjusted by changing pressure or nozzle geometry to adapt to different micro-particle sizes and properties, providing both precision and environmental versatility
Solution Approach 2:
The patent employs a dynamically adjustable water jet system where the capture force can be modified by changing hydraulic pressure, flow rate, or nozzle geometry. This dynamic adjustment capability allows the system to adapt to different micro-particle characteristics and environmental conditions while maintaining capture precision
